A Prospective Study to Evaluate Robot Assisted Total Knee Replacement Outcomes

A Prospective Study to Examine Patient Satisfaction, Function, and Limb Alignment Outcomes for Mako Versus Non-Mako Total Knee Replacements

This study aims to see if outcomes for patients that receive the traditional total knee replacement surgical technique are different than the outcomes for patients that receive robot-assisted total knee replacement. The outcomes we will be tracking include:

1. Patients' self-reported awareness of their artificial joints during activities of daily living;
2. Patient's self-reported pain, other symptoms, function in daily living, function in sport and recreation, and knee-related quality of life;
3. Patients' self-reported general health perceptions, physical functioning, role limitations due to physical and emotional problems, bodily pain, energy-fatigue, social functioning and mental health;
4. The accuracy of implant placement and limb alignment

Inclusion Criteria:

1. Age 18 or older
2. Diagnosed with primary osteoarthritis and cleared to undergo total knee arthroplasty at the Virtua JRI
3. Willing to provide informed consent, participate in study, and comply with study protocol

Exclusion Criteria:

1. Pregnant or contemplating pregnancy prior to surgery;
2. Worker's compensation or personal injury related to knee (clinical outcomes have been shown to be less predictable and often poorer in this patient group; there may also exist potential issues with reimbursement)
3. Post-traumatic arthropathy (clinical outcomes have been shown to be less predictable; pre-operative deformity and risk factors are greater and difficult to propensity-match between groups)
4. Self-pay patients or patients whose insurance are known to typically decline reimbursement for preoperative CT scans
